Automobile toy

ABSTRACT

An automobile toy, including, a wing member; and a stay member attaching the wing member to the automobile body with the stay member put between the wing member and the automobile body, wherein the stay member includes a bent portion bent into a front and rear direction of the automobile body.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an automobile toy equipped with a wing member.

2. Description of Related Art

An automobile toy equipped with a wing member at its rear end portion has conventionally been known. The attaching structure of the wing member is the one imitating that of a rear wing of an actual automobile. That is, the wing member is attached to the automobile body through the intermediary of two stay members, which are shaped in straight flat plates and are provided to be parallel to each other in the vehicle width direction (see, for example, Japanese Examined Utility Model Application Publication No. Sho 56-31270).

In such an automobile toy, however, the stay members are shaped in straight flat plates, and consequently the stay members are sometimes plastically deformed or broken owing to a local stress concentration when the wing member touches a wall or a road surface by an overturn or the like.

SUMMARY OF THE INVENTION

It is, therefore, a main object of the present invention to suppress plastic deformation and breakage of a stay member to which a wing member is attached.

According to an aspect of the present invention, there is provided an automobile toy, including, a wing member, and a stay member attaching the wing member to the automobile body with the stay member put between the wing member and the automobile body, wherein the stay member includes a bent portion bent into a front and rear direction of the automobile body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an appearance view of an automobile toy 1 of the present embodiment.

As shown in this figure, the automobile toy 1 is a travelling toy imitating an off-road vehicle and is equipped with a front wheel axle 2 for supporting front wheels 21, 21 to be able to be steered right and left; a rear wheel axle 3 (see FIG. 5) for supporting rear wheels 31, 31; a body 4, and a wing member 7.

FIG. 2 is a plan view of the automobile toy 1 from which the body 4 is removed.

As shown in this figure, the front wheel axle 2 is supported by a front wheel chassis 5, and the rear wheel axle 3 is supported by a rear wheel chassis 6.

The front wheel chassis 5 is composed of a lower front wheel chassis 51, which is shaped in an almost flat plate and supports the front wheel axle 2 at a front end portion of the front wheel chassis 5, and an upper front wheel chassis 52 (shown by chain double-dashed lines in FIG. 2), covering a central portion of the automobile body of the lower front wheel chassis 51. The lower front wheel chassis 51 and the upper front wheel chassis 52 engage with each other. An electric circuit board 53 which receives a control signal from a remote controller 8, described later, to drive each portion, is placed on the lower front wheel chassis 51, and the electric circuit board 53 is covered by the upper front wheel chassis 52. Furthermore, a steering motor and a gear mechanism, which are not shown, are mounted on the lower front wheel chassis 51, and a steering rack 54, coupled to the front wheels 21, 21, is supported in parallel with the front wheel axle 2 so as to be movable in a right and left direction. These parts constitute a steering mechanism of the automobile toy 1. The steering motor drives the steering rack 54 right and left through the gear mechanism, and thereby the front wheels 21, 21 change their directions right and left. The automobile toy 1 is thus steered. Furthermore, a battery, not shown, is mounted on the lower front wheel chassis 51.

On the other hand, a drive motor 62, having a motor shaft coupled to the rear wheel axle 3, is mounted in the rear end portion of the rear wheel chassis 6. The rear wheel chassis 6 includes two arms 61, 61, extending forward along both-side portions of the automobile 1, and the rear wheel chassis 6 is formed in an almost U-shaped in a planar view.

These front wheel chassis 5 and rear wheel chassis 6 are coupled to each other by the two arms 61, 61 in the both-side portions of each of the chassis 5 and 6. Respective end portions 61 a of the two arms 61, 61 are coupled to coupling portions 55, provided as projections in the both-side portions of the front wheel chassis 5, with the two arms 61, 61 separated from each other in the vehicle width direction, with the rear end portion of the front wheel chassis 5 put between the arms 61, 61.

FIG. 3 is a sectional view viewed from arrows A in FIG. 2, and FIG. 4 is a sectional view viewed from arrows B in FIG. 2. In addition, FIG. 3 shows the figure in which gaps between each part are widened in order to make the figure easy to understand.

As shown in FIG. 3, a hemispherical first projecting portion 52 a, projecting downward and formed on the upper front wheel chassis 52, and a hemispherical second concave portion 51 a, opening upward and formed on the lower front wheel chassis 51, are formed at each of the coupling portions 55. Furthermore, a hemispherical first concave portion 61 b, opening upward complementarily to the first projecting portion 52 a, and a hemispherical second projecting portion 61 c, projecting downward complementarily to the second concave portion 51 a, are formed at each of the end portions 61 a of the arms 61, 61, with the first concave portion 61 b and the second projecting portion 61 c mutually concentric. Each of the end portions 61 a of the arms 61, 61 is nipped by the upper front wheel chassis 52 and the lower front wheel chassis 51 from above and below in such a way that the first projecting portion 52 a and the first concave portion 61 b are slidably fitted to each other, and that the second projecting portion 61 c and the second concave portion 51 a are slidably fitted to each other.

By providing such a coupling structure on the both-side portions, relative rocking between the front wheel chassis 5 and the rear wheel chassis 6 in the horizontal direction and the vertical direction can be allowed, and a road surface following function of the front and rear wheels 21 and 31 and a suspension function of the automobile toy 1 are realized.

Furthermore, each of the two arms 61, 61 is formed in a flat plate inclining toward the inside of the automobile toy 1 in the vehicle width direction in the neighborhood of each of the end portions 61 a as shown in FIG. 4. To put it more minutely, each of the arms 61, 61 is formed to be horizontal at its base end portion, shown by chain double-dashed lines in the figure, and to incline more to the inside as its position becomes closer to the end portion 61 a thereof. By inclining the arms 61, 61 in this way, even if an external force parallel to the vehicle width direction of the automobile toy 1 is applied to each of the arms 61, 61, the arm 61 can disperse the external force according to the inclination angle thereof, and the load which operates on the arm 61 into the vehicle width direction can be reduced.

Furthermore, each of the two arms 61, 61 is made of a twistable elastic member. Consequently, by the twisting of the arm 61, a twist angle between the front wheel chassis 5 and the rear wheel chassis 6 can be enlarged. In addition, because each of the arms 61, 61 can elastically be deformed into the vertical direction, the suspension function of the automobile toy 1 can be strengthened.

FIG. 5 is a partial sectional view of the rear end portion of the automobile toy 1.

As shown in this figure, the wing member 7 is coupled to the rear wheel chassis 6 through the intermediary of a stay member 71, made of an elastic member. The stay member 71 has a bent portion bent in S in the front and rear direction, and only one stay member 71 is attached to the central part of the wing member 7 in the vehicle width direction (see FIG. 1). By attaching the wing member 7 through the intermediary of such a stay member 71, a local stress concentration on the stay member 71 is moderated, and plastic deformation and breakage of the stay member 71 can be prevented, even if the wing member 7 touches a wall or a road surface owing to an overturn or the like of the automobile toy 1.

One end of a spring member 63 is fixed to the front end portion of the stay member 71, and the other end of the spring member 63 is fixed to a projecting portion 52 b at the rear end of the upper front wheel chassis 52. The spring member 63 biases the front wheel chassis 5 and the rear wheel chassis 6 into almost the vertical direction and mainly fulfills the function of a suspension.

Furthermore, locking portions 51 b, 51 b, projecting rearward, are formed in the rear end portion of the lower front wheel chassis 51, and projections 6 a, 6 a, projecting forward, are formed over the locking portions 51 b, 51 b at the front end portion of the rear wheel chassis 6 (see FIG. 2). These locking portions 51 b, 51 b and projections 6 a, 6 a are provided for regulating the relative rocking of the front wheel chassis 5 and the rear wheel chassis 6 in the vertical direction around the end portions 61 a of the arms 61, 61. By regulating the relative rocking of the front wheel chassis 5 and the rear wheel chassis 6 within a predetermined range in such a way, the end portions 61 a of the arms 61, 61 are prevented from being dropped off from the coupling portions 55, and a wiring between the electric circuit board 53 and the drive motor 62 is prevented from being exposed. In addition, the biasing force of the spring member 63 is adjusted so that the locking portions 51 b, 51 b and the projections 6 a, 6 a are stabilized in the state of being separated by a predetermined distance in the vertical direction in their normal states.

FIG. 6 is an appearance view of the remote controller 8 for remotely operating the automobile toy 1.

As shown in this figure, the remote controller 8 is equipped with a lever portion 81 for driving the drive motor 62 to advance or reverse the automobile toy 1, and a steering wheel portion 82 for driving the steering motor to steer the automobile toy 1. The present embodiment is configured so that a user operates the lever portion 81 with the left hand grasping a grip portion 8 a, and operates the steering wheel portion 82 with the right hand.

When the lever portion 81 is moved from its neutral state into the F direction in the figure, the automobile toy 1 is advanced. When the lever portion 81 is moved from its neutral state into the B direction in the figure, the automobile toy 1 is reversed after being braked for a predetermined time. Furthermore, a projecting portion 81 a is formed in the B-direction part of the lever portion 81 which projects into the direction (front side of FIG. 6) opposite to the steering wheel portion 82. Thereby, the remote controller 8 is configured so that an operating finger (for example, the forefinger of the left hand) does not easily slip out at the time of operating the lever portion 81 into the B direction.

The steering wheel portion 82 is configured to be able to drive the steering motor to steer the automobile toy 1 to the left and the right sides by being rotated from its neutral state to the left or the right directions.

Furthermore, the remote controller 8 is equipped with a frequency setting button 84 for switching the operable automobile toy 1, besides an electric power switch 83. By depressing the frequency setting button 84 while a setting signal is output from the automobile toy 1, a setting can be made where the operation of the automobile toy 1, outputting the setting signal, is allowed.

FIG. 7 is an appearance view of a charger 9 for charging the battery of the automobile toy 1.

As shown in this figure, the charger 9 is equipped with an electric power switch 91 and a charge starting button 92, and is configured to be able to charge the battery of the automobile toy 1 by supplying electric power from a built-in battery, not shown, to the battery of the automobile toy 1, by turning on the electric power switch 91 and depressing the charge starting button 92 in the sate of connecting a charging cable, not shown, to the automobile toy 1. Furthermore, the charger 9 is equipped with a power source light emitting diode (LED) 93 and a charging LED 94. Whether the power source is on or off can be judged by whether the light of the power source LED 93 is on or off, respectively. Further, whether the charging state of the charger 9 is “during charging” or “completion” can be judged by whether the light of the charging LED 94 is on or off, respectively.

According to the aforesaid automobile toy 1, the stay member 71 includes the bent portion, bent into the front and rear direction of the automobile toy 1. Consequently, even if an external force into the front and rear direction of the wing member 7 operates on the stay member 71, the external force can be dispersed according to the bent angle of the bent portion. Furthermore, because the bending makes the stay member 71 easy to elastically deform, plastic deformation of the stay member 71 can be suppressed. Furthermore, even if an external force operates on the wing member 7 into the horizontal direction thereof, the stay member is made to be easily elastically deformed, and plastic deformation of the stay member 71 can be suppressed because the stay member 71 is made to be longer by the bending, in comparison with the lengths of the conventional straight stay members.

By the configuration described above, a local stress concentration on the stay member 71, to which the wing member 7 is attached, can be moderated, and plastic deformation and breakage of the stay member 71 can be suppressed.

Furthermore, because only one stay member 71 is attached to the central part of the wing member 7 in the vehicle width direction, an external force operating on the wing member 7 into the direction for inclining the wing member 7 can be received at the minimum moment, in comparison with the conventional two stay members, provided in parallel with each other. Consequently, plastic deformation and breakage of the stay member 71 can further be suppressed.

Furthermore, because the stay member 71 is made of an elastic member, the say member 71 is made to be more easily elastically deformed, and plastic deformation and breakage of the stay member 71 can further be suppressed.

In addition, the present invention should not be interpreted to be limited to the aforesaid embodiment, but it should be understood that suitable changes and improvements can be performed.

For example, although the stay member 71 is configured to include a bent portion in the aforesaid embodiment, the stay member 71 may be the one consisting of the bent portion, that is, the one having no straight line portions.

Furthermore, the shape of the bent portion of the stay member 71 is not limited to the S shape, but may be a dogleg shape, a Z shape, and the like, as long as the bent portion is bent in the front and rear direction. In addition, if the suppression of plastic deformation and the like of the stay member 71 into the direction for inclining the wing member 7 into the horizontal direction is desired, the bent portion of the stay member 71 may be the one bent in the horizontal direction. The “bending” in the present invention is a broad concept including “curving” and “zigzagging,” and the like, regardless of how the bent portion is bending.

Furthermore, as shown in FIG. 8, it is preferable to provide an overturn prevention ring 10, shaped in almost a belt, on the automobile toy 1. The overturn prevention ring 10 is made of a transparent polycarbonate and is fixed to the back surface of the lower front wheel chassis 51 to enclose the automobile toy 1 at almost the central part in the front and rear direction. Furthermore, two projections 10 a, 10 a are formed at the top end of the overturn prevention ring 10 projecting into the front and rear direction. The positions of the two projections 10 a, 10 a in the circumferential direction are different from each other, with the center of the vehicle width direction between the two projections 10 a, 10 a. By providing such an overturn prevention ring 10, the automobile toy 1 can be protected, and further if the automobile toy 1 is likely to overturn, the overturn prevention ring 10 touches a wall or a road surface to make it possible that the automobile toy 1 restores its posture. Furthermore, even if the automobile toy 1 has been inverted, the projections 10 a, 10 a make the inversion state unstable, because the automobile toy 1 is supported by a pointed end of one of the projections 10 a, 10 a. Therefore, the posture of the automobile toy 1 can be restored by causing a reaction by steering the front wheels 21, 21 or driving the rear wheels 31, 31.
